Hello here is a solution :
80 times could Kaitlyn expect to pull out a blue chip.
<u>Step-by-step explanation</u>:
- The total number of chips in the bag = 7 white+5 red+ 8 blue = 20 chips.
- Probability (blue chip) = number of blue chips / total chips
P(blue) = 8/20
She does this 200 times.
P(blue) for 200 times = (8/20)
200 = 80.
Answer:
(a / 4) + 1.5 = b
Step-by-step explanation:
1.5 + (a / 4) = b
Arrange:
(a / 4) + 1.5 = b
Final Answer:
(a / 4) + 1.5 = b
1) 3x-7y=2
2) If you're solving for x, you want to isolate it, so move the -7y to the right:
3x = 7y + 2
3) Now, to get x by itself, you divide both sides by 3
3x/3 = (7y + 2)/3
4) You get:
x = 7/3y + 2/3
